These days, vehicles rely upon sophisticated engine computers to control a series of actuators in an internal combustion engine. This ensures proper engine performance, since the actuators adjust to optimize the fuel load to feed combustion, control exhaust levels, and keep your engine running at peak performance.

How Engine Computers Work

The engine computer, also called an Engine Control Unit (ECU), Engine Control Module (ECM), or Powertrain Control Module (PCM), adapts to changing conditions and your driving style to maximize both efficiency and safety. It takes information in from a range of sensors, allowing it to regulate the fuel injectors, adapt the engine's idle speed, control the spark plugs, govern the ignition system, send commands to the camshaft and transmission, and warn you of any issues. In summary, it's the QB that runs your engine every time you start your premium car or SUV.
